There is a Croatian company which was named “ELMECH d.o.o.” and produced artillery ammunition in the 1990s (also sniper rifles). They went out of business in 2006 (as per a web entry).
Today there is an entry of a company named “ELMECH RAZVOJ d.o.o.” with a different city but identical product profile.
I assume the company was restructured (new investors and new location) after 2006.
Unfortunately I can not find any usefull entry on the “new” company (also not on the old one) like their website and logo etc…
